I favor the first act restructuring (Exegol, then Rey, then Falcon mission). Keeps the actual edit conservative in terms of story, but reduces the breakneck pacing.

The Goonies moment with the Dagger has to go. When 3PO reads the inscription he speaks some kind of coordinates, those can be easily handwaved as the actual spot on the wreckage where the Wayfinder lies. Add the Sith whispers while Rey’s climbing the ruins and you’ve got a mostly credible scene.

I don’t know if cutting Leia’s knowledge of Rey’s lineage would work seamlessly, because one of the main things that makes Rey change her mindset during the Luke pep-talk moment, is the fact Leia still trained her and accepted her despite the risk. But I agree Luke should be the one that didn’t know, at least prior to his passing (He was isolated from the Force, and Luke knowing about Palpatine doesn’t fit that well with his genuine surprise and fear of Rey’s dark side in TLJ).

It would be great if DOTF can be incorpored in some way during the faceoff between Sidious and Rey.

Have you considered that dialogue reshuffle someone did for the opening scene, where Palpatine establishes the Dyad as being a thing from the beginning?
